I have three California White Leghorn hens. They are now 22 weeks and the combs are turning brighter red and they are fighting amonst themselves a bit. My rooster is attempting to keep the peace, but they are showing signs of fighting on the combs. Hopefully they will work it out soon!

This is how they look now at 22 weeks.
This bottom pic is of one at about 18 weeks.
